This time on Jonathan Chicken’s Blue World,sharks that disguise from fish? Hello, I’m Jonathan Chicken and welcome to myworld! The massive, chilly, and stormy Atlantic Oceanis often called a really unforgiving place for ships.

However the waters off the outer banks of NorthCarolina are particularly harmful.

These tough waters with hidden shallow shoalshave taken hundreds of ships over the previous a number of hundred years.

Moreover, throughout World Battle 2, German submarinespatrolled these waters.

They snuck up on unarmed service provider ships, andtorpedoed them, in an effort to disrupt American provide traces.

In a small space that got here to be often called “TorpedoAlley,” lots of of ships had been misplaced.

Many individuals had been rescued, however hundreds werenot.

At this time we name it the Graveyard of the Atlantic,and most of the shipwrecks are accessible to leisure scuba divers.

Whereas there may be typically nice lack of life associatedwith a sinking ship, life returns to the ship because it slowly turns into the center of a thrivingcommunity of marine life.

A shipwreck might appeal to marine life from milesaround, as a result of it’s the one factor providing shelter and hiding spots on an in any other case featurelesssea flooring.

The wrecks are engulfed in faculties of thousandsof fish.

However the wrecks of the Graveyard have alsoattracted one thing else.

It’s 6 AM in Atlantic Seaside, North Carolina,and I’m boarding the dive boat Atlantis.

I’m right here to discover the shipwrecks of theGraveyard, and hopefully, meet some sharks.

My crew and I load gear aboard and head outas the solar is rising forward of us.

My pal Captain Bobby Edwards has been leadingdive expeditions right here for nearly 40 years.

He is aware of the waters and has a really feel for thewrecks.

He is aware of the place the sharks are.

It’s a two hour run to our vacation spot,the wreck of the Spar.

After we arrive, I go well with up.

I can’t wait to get right down to the wreck andtry to seek out some sharks.

Eighty ft down, the Spar is sitting upright,at a jaunty angle, with that basic shipwreck look.

The wrecks are far sufficient offshore that theyare bathed within the heat clear water of the Gulf stream, which flows like a river fromthe Caribbean up the east coast of the USA.

And as I anticipated, there is no such thing as a scarcity offish—enormous faculties of Tomtate grunts swarm across the wreck.

The grunts are chased by Jacks, which herdthem like sheep, whereas searching for stragglers to select off.

I see quite a lot of fish motion, however no sharks.

Contained in the wreck, not a lot is occurring atall.

There’s a rest room with a view.

With out discovering any sharks, our crew ascends.

I’ve to spend a couple of minutes doing a decompressionstop on the anchor line earlier than I can floor.

We determine to strive a distinct wreck, so captainBobby strikes the boat a brief distance to the wreck of the Aeolus, fairly well-known for sharks.

Quickly I’m again within the water and heading tothe backside.

Down on the wreck, the fish motion is intense! The jacks are chasing not simply the grunts,however enormous numbers of smaller silvery fish referred to as scad.

It’s full mayhem on the wreck with fishdarting each which manner making an attempt to keep away from the jacks, but nonetheless stay within the security of colleges.

A few of the faculties are tightly packed arounddark objects which are transferring by way of the water.


You would possibly suppose that the fish can be crazyto cling round a shark nevertheless it’s the right safety.

The scad are too small and maneuverable tobe caught by a giant shark.

So long as they avoid the shark’smouth, they’re unlikely to develop into shark meals.

However the jacks would make a a lot better lunchfor the shark, so they offer the shark a large berth.

The scad are utilizing the sharks as bodyguards.

Sadly for the sharks, no one askedthem in the event that they wished to be bodyguards.

It doesn’t seem to be there may be a lot theycan do about it although.

However, the sharks have discovered how theycan disguise from the fish.

They take turns slipping contained in the wreck.

Down right here, the scad appear to calm down a bit, andthey don’t cling fairly so near the shark.

The shark looks as if she is taking a breakfrom all the joy.

As she hovers contained in the wreck, the fish mayhemis nonetheless happening exterior within the background.

However that’s not essentially the most uncommon factor goingon right here.

This shark is hovering in place with perfectbuoyancy management.

It’s extraordinarily uncommon to see a shark hovering.

Bony fish have a swim bladder they will useto alter their buoyancy, to allow them to hover in place.

Sharks don’t have any swim bladder and sink if theystop swimming.

Most sharks both maintain swimming all of the timeto keep up off the underside, or settle right down to relaxation at times.

Hovering is simply not an choice.

Sand Tigers nevertheless aren’t about to letsomething like anatomy maintain them from hovering.

They sometimes rise to the floor andtake a giant gulp of air, turning their abdomen into an improvised swim bladder.

Good buoyancy.

It might probably’t be simple to get it proper, however thesharks know simply how a lot air they should gulp down in an effort to hover inside a shipwreck90 ft deep.

This shark has a rusty fishing hook stuckin her mouth.

Happily, the fisherman let her go, butdidn’t wish to go close to her tooth to take away the hook.

So the road was reduce.

However the hook will rust away in just a few weeks,leaving a rusty stain in her mouth as proof of the hazards of fishing hooks.

The tooth of the Sand Tiger shark are the ultimatefishing hooks.

Lengthy, skinny and wickedly-sharp, they resemblea mouthful of needles, pointing backwards so nothing can wiggle out.

These tooth are beautifully designed to catchslippery fish.

However they aren’t slicing tooth.

Sand Tigers don’t take bites out of largeprey.

They swallow smaller animals entire.

The Graveyard of the Atlantic might have begunwith the loss of life of lots of of ships.

However new life is springing from these wrecks.

As synthetic reefs, they supply habitatfor fish, invertebrates and even sharks, serving to the ocean get better from many years of overfishing.

Each time I go to the wrecks of North Carolina,I’m amazed by the expertise, and astonished greater than ever by the wonder and complexityof the Blue World.
